REFUSE-DESTRUCTOB.

. To all wlw/m. it may cmwanz'I l Beit known thatI FRANK Pnucrlnnnnk, British subject, and resident of Derby,` county of Derby, England, have invented certain new -and 'usefulImprovements. in Refuse-Destruotors, of which the following is a specification.

This invention relates to refuse destructors ofthe type: referred to inmy previous application forZ patent Serial No. 386098 -filed on the 29th day of'JuLy 1907, and isdesignedto provide a neat andI compact arrangement of furnace for consuming com'- paratively wet refuse.'

In the specification of the prior application referred tomeans are described for driving oii' the Whole or a large'portion of the moisture contained in the 'refuse before.

-it -is passed to the .bright part 'of thetire,

and the present application relates to a' .special constructionof destructor in which the'prlor invention 1s lincorporated.

The invention Will befully described with y referenceto the accompanying drawings.

Figqll is a. perspective"sectional View of Toward one end of the structure a grate X composed of fire bars is constructed which may if desired bedivided into twoor more separate grat-es by 'low' iv'alls or divisions 35,.-.which Aextend above the dividing walls of theashpits C. Behind the lire bars is a1'- ranged ai drying platt or `table Lg such'as described in the speciication of the priorapplication, to receiv(l (he fresh or wet refuse 40 through which the hotproducts'of combustion are directed through the openings H in the Wall. M. At the other cud of the struture frofni the Z grate Yis formed the combustion chamber B which communicates by means of a passage through the Wall with the boiler Hfrom which'the'products of combustion (see 'the plain arrowA Fig. 4)

The air to 'aid combustion (see the {cath-'- ered arrow Fig. it) enters by the inlet JL and 'becomes heated by passing through the air specification o: Letters raten-tl Patented Mar. 14, appunti mea Augier ze, 1901. serial No. 390,126;A
